Analytical Treatment of Two-Phase Infiltration
Publication: Journal of the Hydraulics Division
Volume 96, Issue 12
Abstract
An approximate analytical treatment for the problem of one-dimensional infiltration into a homogeneous porous medium is presented. Movement of both the air phase and the water phase is considered. The procedure assumes that capillary pressure can be neglected in the saturation equation, whereas it is retained in an integral equation for the unknown total flow. The two equations are solved in a step-wise manner to yield the saturation profile, and the infiltration rate at any time. Infiltration rate curves are obtained for a number of situations involving different boundary or initial conditions or both. Comparisons are made with results obtained from a finite difference solution.
